Abstract

New organic material has been synthesized and single crystals were grown from aqueous solution. Single crystals of 4-methylpyridinium picrate have been grown by slow evaporation technique acetone as a solvent at room temperature. Single crystal X-ray diffraction study on grown crystals shows that it belongs to monoclinic system. Fourier transform infrared (FTIR) spectroscopic study was performed for the identification of different modes of functional groups present in the compound. The thermal stability of the compound has been determined by TG-DTA curves. The result shows that the material starts decomposing at 171.50 °C. The UV-visible transmission spectrum has been recorded in the range 190-900 nm. The photoconductivity study confirms the negative photoconductive nature of the sample. The dielectric measurement of the compound has been analyzed using dielectric analysis. Laser damage threshold value for the crystal was measured.
